Answers

Answer 1

9514 1404 393

Answer:

  either

Step-by-step explanation:

They could represent either:

  2^2 = 4 . . . a rational number

  2^(1/2) = √2 . . . an irrational number

The fact that a number has an exponent does not make it either rational or irrational.

Additional comment

You can also consider irrational numbers with exponents.

  (∛2)^2 = 2^(2/3) . . . irrational

  (√2)^2 = 2^1 . . . . . . rational

Which is an equation of a line with a slope of 1/2 that contains the point (-4,7)?

Answers

Answer

We know that this is a straight line, so it will follow the slope intercept equation:
y = mx + b.
To solve this problem, we need to plug in the x and y values for one point to get b, and then we will know the equation for the line, which is valid for all points.
x = −4

y = −3

m = 1/2
Let's start by solving for b:
b = y − mx
Now we can plug in numbers:
b = −3 − (1/2 × −4)

b = −3 − (−2)

b = −3 + 2

b = −1
Now that we know m and b, we can plug into our original equation:

The equation is y = 1/2x − 1.

Statment: Find the measure of the angle indicated by 19x+5

Options: 130
50
80

Answers

Answer:

100

Step-by-step explanation:

These two angles are corresponding which means they add up to 180.

so... 19x+5+(16x)=180

If you simplify...

35x+5=180

Then solve for x...

35x=175

x=5

Then take that 5 and fill it into 19x+5...

19(5)+5

Answer:

(- 4, - 2 )

Step-by-step explanation:

Given the 2 equations

- 4x + 4y = 8 → (1)

y = - 2x - 10 → (2)

Substitute y = - 2x - 10 into (1)

- 4x + 4(- 2x - 10) = 8 ← distribute and simplify left side

- 4x - 8x - 40 = 8

- 12x - 40 = 8 ( add 40 to both sides )

- 12x = 48 ( divide both sides by - 12 )

x = - 4

Substitute x = - 4 into (2) for corresponding value of y

y = - 2(- 4) - 10 = 8 - 10 = - 2

Solution is (- 4, - 2 )

The economic lifetime of a particular model is only four to six months, which means that Slaq has very little time to make adjustments in production capacity and supplier contracts over the production run. For a soon-to-be-introduced notebook, Slaq must negotiate a contract with a supplier of motherboards. Because supplier capacity is tight, this contract will specify the number of motherboards in advance of the start of the production run. At the time of contract negotiation, Slaq has forecasted that demand for the new notebook is normally distributed with a mean () of 10,000 units and a standard deviation () of 2,500 units. The net profit from a notebook sale is $500 (note that this includes the cost of the motherboard, as well as all other material; production, and shipping costs). (Hint: ! = $500) Motherboards cost $200 and have no salvage value (i.e., if they are not used for this particular model of notebook, they will have to be written off).
